Who prospects SIC 81300 companies
These are classic local service businesses, so the sellers are familiar ones. Insurance brokers offer public liability. Accountants chase new incorporations. Job scheduling and quoting apps, equipment and chemical suppliers, and franchisors recruiting operators all work the same lists. Commercial cleaning and facilities firms also appear on procurement radars, when offices, schools and managing agents look for contractors. A weak website usually marks a word-of-mouth operator, and the poor-website filter finds the audience that website builders and local SEO services convert best. Growth marks firms moving from domestic work into contracts.
Lead generation for trades & construction →How to read SIC 81300
SIC 81300 is a five-digit code, and the digits are not arbitrary. The first two, 81, are the division, services to buildings and landscape activities. Add the third and you have group 813; the fourth narrows it to a class, and the fifth to the subclass, which is the level Companies House actually asks a company to pick. The whole division sits under section N, administrative and support service activities, the broadest tier there is. Reading a code left to right therefore goes from a whole sector down to one activity.
More on how SIC 81300 is built
A company chooses its own codes when it incorporates and can change them on any confirmation statement. It may list up to four, and Companies House does not check whether they are right. That is why 81300 is worth reading as a claim the company made about itself rather than as a verified fact, and why the first-position and any-position counts above differ.
Measured on the August 2026 register, the busiest registered-office post towns for 81300 are London (1,617), Glasgow (303), Birmingham (239), Manchester (227) and Bristol (220). Those are registered-office locations, which is where the paperwork sits rather than necessarily where the work happens, so treat them as where to start looking rather than as a service area.
Using SIC 81300 as a filter
23,071 companies is 0.44 per cent of the 5,190,464 active companies on the UK register, and ranks 81300 second most used of the 8 codes we track in division 81. That is the pool before any filter. Whether it is a big market for you depends on what you sell, but it is the number every other filter on this page cuts down from.
More on filtering by SIC 81300
17,044 companies put 81300 first and a further 6,027, 26 per cent, list it in one of their other three SIC slots. That gap is the difference between a tight list and a broad one. First-code-only is the safer filter when you are writing to them; matching any position is worth it when you need the volume.
These companies are spread out. London is the largest single cluster at 7 per cent and the top five post towns together hold only 11 per cent, so the remaining 89 per cent sits across the rest of the country. A regional filter narrows this list without gutting it, which makes it a reasonable code to work territory by territory.
In practice the code on its own is rarely the whole filter. Pair 81300 with an incorporation date to catch companies in their first months, when they are still choosing suppliers, or with a filing deadline to reach them while the year end is on their mind. A worked example for this code: 81300, registered office in London, incorporated in the last ninety days, which turns a 23,071 company pool into a list you can write to in an afternoon. Add the poor-website filter if what you sell is a website, or a recent change of officer if you sell to whoever just took the job. Every company you pull carries the Companies House record, the director's name, a verified website and a verified email, and the ones we cannot complete are not charged.
